A 25-year-old man died earlier this week when he was electrocuted while walking through floodwaters from Tropical Storm Harvey to feed his sister’s cat.

Andrew Pasek was wading through water with a pal in Bear Creek Village on Tuesday when he “got too close to an electrical wire that was still running hot,” his sister told KPRC Houston.

“It was just a terrible mistake, accident that shouldn’t have happened,” Alyssa Pasek said. “They were going to wade in the water, they were only in about knee-deep water and walking through the neighbors’ yards because the water was more shallow.”

Pasek, who was going to check on his sister’s flooded home and leave food for her cat, warned his friend to stay away as he was electrocuted.
